13. Análise da associação dos protocolos de roteamento AODV e DSR com o algoritmo Gossip, sistema de Quorum e com um novo algoritmo de economia de energia, PWSave. / Association analisys of the routing protocols AODV and DSR with Gossip, Quorum system and a new algorithm, PWSave.
This work studies the implementation of the Quorum system associated with the Gossip algorithm, the implementation of a new power saving algorithm - the PWSave - and the routing protocol AODV in a scenario with and without failures of an ad hoc network with mobility. It has been chosen to implement this work in an environment of simulation, because the mathe

14. Interpolation functions analysis in finite volume method / Análise de funções de interpolação no método de volumes finitos
In this work, the mathematical and computer modeling in the analysis of the interpolation functions in the Finite Volume Method was developed. The equations were integrated in the control of volume in which frontiers the advective and diffuse flows must be evaluated. The interpolation function, which main objective is to connect the nodal points, was used to

15. Mathematical modeling of an industrial process for chlorine and caustic manufacturing using brine electrolysis aiming at its optimization. / Modelagem matemática de um processo industrial de produção de cloro e soda por eletrólise de salmoura visando sua otimização.
The present work consists on the development of a mathematical model on an industrial chlorine and sodium hydroxide production plant, aiming at the optimization of production efficiency and costs saving concerning electrical energy and vapor consumption. Two process steps were considered in the study: electrolysis and NaOH-liquor concentration by evaporation

16. Modeling and mapping of thermal environment to evaluate the performance of broiler chickens lodged in acclimatized housing / Modelagem e zoneamento do ambiente tÃrmico para avaliar o desempenho de frangos de corte criados em galpÃes climatizados
The objective of this work was to develop and validate a mathematical and computational model to predict thermal environment (air temperature, relative humidity, temperature-humidity index â THI and environmental index for broiler chickens productivity â EPIbc), main physiological responses (skin temperature â TS, rectal temperature â TR and respiratory

17. Monte Carlo methods in nonlinear filtering theory.
This thesis is focused on two basic aspects of the Control Problem: the stochastic modelling of physical systems, and Monte Carlo-based numerical approximation of the nonlinear filtering problem solution. In the first topic this thesis concerns about clarifying some issues in the mathematical modeling of continuous-time systems with Brownian motion. The hypo

18. An investigation of singularities in robot kinematic chains aiming at building robot calibration models for off-line programming
Robot Calibration is a term applied to the procedures used in determining actual values that describe the geometric dimensions and mechanical characteristics of a robot or multibody structure. A robot calibration system must consist of appropriate robot modeling techniques, accurate measurement equipment, and reliable model parameter determination methods. F

19. Fault detection and diagnosis in robotic manipulators via artificial neural networks. / Detecção e diagnóstico de falhas em robôs manipuladores via redes neurais artificiais.
In this work, a new approach for fault detection and diagnosis in robotic manipulators is presented. A faulty robot could cause serious damages and put in risk the people involved. Usually, researchers have proposed fault detection and diagnosis schemes based on the mathematical model of the system. However, modeling errors could obscure the fault effects an

20. PROCESS CONTROL SYSTEMS : DEPENDABILITY AND PERFORMANCE MODELING
Today, a wide variety of computer systems are required to react automatically to various events generated by external processes and/or human operators. An important class of these process control systems, called hard real-time systems, need to respond to events under severe timing constraints expressed in terms of deadlines and earliest starting times. In ge

21. Membrane Capacitance Measurements Revisited: Dependence of Capacitance Value on Measurement Method in Nonisopotential Neurons
During growth or degeneration neuronal surface area can change dramatically. Measurements of membrane protein concentration, as in ion channel or ionic conductance density, are often normalized by membrane capacitance, which is proportional to the surface area, to express changes independently from cell surface variations. Several electrophysiological protoc
